Paints and varnishes - Determination of density - Part 1: Pycnometer method (ISO/DIS 2811-1:2022)

ISO 2811-1:2016 specifies a method for determining the density of paints, varnishes and related products using a metal or Gay-Lussac pycnometer.
The method is limited to materials of low or medium viscosity at the temperature of test. The Hubbard pycnometer (see ISO 3507) can be used for highly viscous materials.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to

the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

www.iso.org/iso/foreword.html.

This document was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee

SC 9, General test methods for paints and varnishes.

This fourth edition cancels and replaces the third edition (ISO 2811-1:2016), which has been technically

revised.
The main changes are as follows:

— a requirement to de-areate the sample prior to the determination in order to achieve reproducible

results for the density has been added to 8.2;

— the text has been editorially revised and the normative references have been updated.

A list of all parts in the ISO 2811 series can be found on the ISO website.

Any feedback or questions on this document should be directed to the user’s national standards body. A

Paints and varnishes — Determination of density —
Part 1:
Pycnometer method
1 Scope

This document specifies a method for determining the density of paints, varnishes and related products

using a metal or Gay-Lussac pycnometer.

The method is limited to materials of low or medium viscosity at the temperature of test. The Hubbard

pycnometer (see ISO 3507) can be used for highly viscous materials.
2 Normative references

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

ISO and IEC maintain terminology databases for use in standardization at the following addresses:

— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1
density
mass divided by the volume of a portion of a material
Note 1 to entry: It is expressed in grams per cubic centimetre.
4 Principle

A pycnometer is filled with the product under test. The density is calculated from the mass of the

product in the pycnometer and the known volume of the pycnometer.
5 Temperature

The effect of temperature on density is highly significant with respect to filling properties, and varies

with the type of product.

For international reference purposes, it is essential to standardize one test temperature, and

(23,0 ± 0,5) °C is specified in this document. It can be more convenient, however, to carry out comparative

testing at some other agreed temperature, for example (20,0 ± 0,5) °C, as specified by relevant weights

and measures legislation (see B.2).

The test sample and pycnometer shall be conditioned to the specified or agreed temperature, and it

shall be ensured that the temperature variation does not exceed 0,5 °C during testing.
